The so-called sea treasure hunting companies are some submarine salvage companies.

In the high seas, whether at sea or under the sea, there is no owner, and whoever discovers it first belongs to whomever owns it. As a result, many deep-sea expeditions have been created that specialize in detecting shipwrecks on the seabed and salvaging the materials inside the wreck.

Particularly close to China's coast and along the Maritime Silk Road, many of the Song and Ming Chinese shipwrecks were filled with fine porcelain, gold and silver.

Sun Yaoru's Dayue Deep-sea Company, although it is now mainly engaged in deep-sea mineral mining, has not given up the salvage business of deep-sea shipwrecks.

Over the past two decades, he has donated all 15 of his salvaged Song and Ming shipwrecks to the Chinese government.

"Hey, Brother Qingyun, don't you want to say that this kind of thing is something that Old Man Guiyi has already considered, so he has taken the necessary defensive measures, right?"

"Haha, it's not impossible," Wei Qingyun asked for permission from Yamamoto Shintora and roughly talked about Yamamoto Guiichi's life as a spy.

"What? Can't even take a special high class with him? You're not bragging for him, are you? ”

"How can it be, a person's career, will deeply affect his way of thinking, life and work habits, I once tried to interpret some of the old man's post-war behaviors, speeches, articles, but it is not leaky, there is no way to find a little trace of his first half of life from some of his later speech and behavior, you think about it, such a person, his caution, is simply terrifying."

"And how did he hide it?"

"First of all, he will use some anti-radar detection equipment, such technology and equipment were very mature at that time, with his experience as a spy, it is not difficult to think of this, after this, I think there are two possibilities, first, the cargo is specially packaged and sunk to the bottom of the sea, second, there may be some desert island nearby, he simply hid the whole ship on the island."

"Then tomorrow we will go back to China and go to the Guo family to ask for the logbook of the Fuhua." Xie Lingyan said.

"No," Wei Qingyun shook his head, "Let's go directly to Taiwan, you send a secret call to your leaders, ask them to send people, the itinerary and communication must be kept secret, so as to ensure speed, because we not only have to find those things, but also have to be careful of Donald's gang." ”

"Okay." Xie Lingyan nodded.

Wei Qingyun and Xie Lingyan found Sun Zhongwen, and the three of them took the Sun family's private plane and rushed to Taiwan overnight.

Early the next morning, they received a message from Lin Xiaohu - he had made a three-dimensional model of the relationship between Momotaro and Ishida based on the photos provided by Yamamoto Nobuta, and calculated the angular relationship between Yamamoto and Fuhua at that time.

Based on the coordinates of the Fuhua's hull, Yamamoto is located at about eight o'clock in the Fuhua's direction, and is roughly at an angle of 55 degrees to the hull.

Lin Xiaohu was in Yixian Island, the undersea fortress of the Sun family, and used the top computer and communication equipment there to give everyone technical support.

In addition to Sun Zhongwen who has been following Wei Qingyun and others, Sun Yaoru also dispatched an offshore operation platform and a civilian sea exploration submarine from the deep sea of Dayue to the high seas in northeast Taiwan and is on standby at any time.

In this sea exploration and treasure hunting operation, Dayue Deep Sea will undertake all the technical equipment and personnel support.

Yamamoto Nobuta is inconvenient to show up, but he will give support in terms of connections - it is uncertain whether the Rising Sun Maru, or the treasure, is on the high seas, and whether there will be right-wingers interfering, and if these problems arise, he will intervene to mediate and settle them.

Because it involves the issue of World War II war criminals and evidence of the Japanese invasion of China, the Chinese government is not prepared to come forward directly, and still limits the incident to civilian behavior, but will send secret troops against Donald and company to give combat support.

At 10:30 a.m., Xie Lingyan received a document sent through the secret mail system of the public security.

The Guo family was very cooperative and found all the logbooks of the Fuhua in 1944 as soon as possible.

The logbook clearly records the rescue of Koji Ishida.

Moreover, through the Fuhua's logbook, it also confirms the authenticity of Yamamoto Guiyi's memory fragments.

At that time, the Fuhua was returning to Keelung from the port of Tokyo, and after encountering heavy fog, it deviated from its course, and also encountered a strange magnetic field.

However, fortunately for the Rising Sun Maru, before entering the magnetic circle, the Fuhua discovered the signal anomaly through the radar system, and through technical analysis, it was concluded that the magnetic circle was about 12 nautical miles in diameter.

In order to circumvent the magnetic circle, the Fuhua deviated from course again.

Because it was a time of war, the second mate on the Fuhua conducted a routine interrogation of Koji Ishida after rescuing him.

Although Koji Ishida lied most of the content, one thing should be true - after leaving his boat, he rowed straight for six and a half days, rowing at a constant speed for 11 hours a day until he met the Fuhua.

The latitude and longitude coordinates of Koji Ishida rescued by Fuhua are approximately N24°16′ north latitude and E130°05′ east longitude.

The record does not mention the speed at which Koji Ishida rowed, only that it was at a constant speed, and other conditions include the appearance of the lifeboat that Wei Qingyun read in his brain, as well as the style of the oars.

Based on these data, Lin Xiaohu deduced the approximate speed of Koji Ishida's ship, and finally gave the approximate direction of the Rising Sun Maru—N28°03′ north latitude and E142°08′ east longitude.

This data is not exact, but it is quite specific relative to the Pacific Ocean as a whole.

The offshore operation platform and submarine in the deep sea of Dayue also arrived at the designated coordinates at about 7 o'clock in the evening.

Thirty minutes later, that is, at half past seven in the evening, Wei Qingyun and the three of them took a helicopter to arrive at the offshore operation platform in the deep sea of Dayue.

The so-called offshore operation platform is a large ship, but it is more like an aircraft carrier than ordinary ships.

The ship is equipped with various satellite equipment, sonar equipment, drilling platforms, aprons, diving platforms, and three small submersibles, which can dive to a depth of 4,000 meters.

The person in charge of the operation in Dayue Deep Sea is called Sun Meiru, a native of Guangdong, and Sun Zhongwen's cousin in China.

Sun Meiru first searched the situation in the nearby 30 nautical miles through the satellite system, and found two small islands and seven isolated islands.

A group of drones was immediately dispatched to conduct an in-depth survey of all the islands.

They didn't sleep well last night, Wei Qingyun and the three of them were tired in their excitement, Sun Meiru persuaded them to sleep, the radar equipment on the operating platform can detect the situation in the sea area within a radius of 100 miles around the clock, and once a suspicious ship or plane enters, it will wake them up in time.

How can young people be persuaded to toss for two months, just waiting for this day.

"Let's take a look around first, if you don't turn around, you will definitely lose sleep tonight." Xie Lingyan pushed and shoved, encouraging Sun Zhongwen to hurry up and fly the plane.

The three of them hit it off and flew towards the two islands first.

"Hehe, it's the first time to do something for the motherland, and I'm really excited." Sun Zhongwen said from the bottom of his heart.

"Hahahaha, don't worry, young man, there will be a place where the motherland needs you in the future, come on."

The three of them talked and laughed excitedly, and soon reached the sky above an archipelago.

Sun Zhongwen turned on the searchlight, thermal radar, and metal detection radar, starting with the nearest island, and checked it little by little.

The first archipelago, called the Archipelago, is an exaggeration, consisting of three small islands less than three square kilometers in size, and a small reef.

The situation on the reef is clear under the searchlight, and the topography of the three small islands is also very simple, just three raised round hills, and the vegetation is quite lush, but there is no corner that looks like it is enough to hide a large ship.

There was silence on the radar, not even a single noise.

The excitement of the three began to subside, and their hearts became heavy.

At this time, Sun Zhongwen received an instruction from the operating platform.

"Treasure Hunt One, please return immediately, Treasure Hunt One, please return immediately."
